High levels of Lp(a)—a fatty particle similar to LDL cholesterol—may double or triple a person’s risk of a heart attack. About one in five adults may have elevated levels, which also raises the risk of stroke and aortic stenosis. Unlike LDL, which rises with age and is influenced by diet and exercise, Lp(a) remains largely constant over a person’s lifetime, so a one-time test suffices for screening. Lp(a) testing is becoming more common now that five promising new Lp(a) therapies are in development.

Social media sources may share misleading information about canola, soybean, and other seed oils. But these oils, which consist mostly of unsaturated fat, can be a good source of heart-healthy fat when combined with whole, fresh foods rather than in processed foods like crunchy, salty, or sweet snack foods. Consuming unsaturated fat in place of saturated fat (found mainly in animal-based foods) is linked to a lower risk of heart attack and death from heart disease.

After a heart attack or stent placement, people typically take a combination of aspirin and another antiplatelet drug. After one year, the new standard practice is to stop the aspirin, in contrast to the previous practice of stopping the other drug.
